Investigating the Effect of Surface Area on the Rate of Reaction

The video discusses the topic of investigating the effect of surface area on the rate of chemical reactions. The presenter explains the concept of collision theory and how chemical reactions occur when particles collide with each other. The focus of the video is on studying the reaction between marble chips and hydrochloric acid and how the surface area of the chips affects the rate of the reaction. Two experimental methods are discussed, one involving measuring the time taken for the chips to disappear and the other involving measuring the amount of carbon dioxide collected over a set time. The presenter demonstrates the procedures for both methods and explains how the results can be analyzed using equations.
